[0002] Municipal pipelines buried underground in cities include water supply pipelines, drainage pipes (channels), power lines, telecommunications lines, gas pipelines, heat pipelines, oil pipelines and other pipelines and their affiliated municipal facilities. In recent years, with the advancement of urbanization and the development of urban construction, the types and number of underground pipelines have increased rapidly, and people have paid more and more attention to the protection measures for underground pipelines in municipal engineering construction.

[0003] In the prior art, in order to protect the pipelines buried under the road, a protection frame is added to the outside of the pipeline. The protection frame improves the load-bearing capacity of the pipeline and thus increases the service life of the pipeline. However, the pressure generated at the moment of contact when a car is driving on the road is relatively large. During the long-term use of the protection frame, the protection frame will be damaged, and the protection of the pipeline will be lost. Utility Model Content

[0007] Preferably, threaded holes are formed at equal intervals on the device frame wall and the device frame seat, and threaded rods are meshedly connected in the threaded holes.

[0008] Preferably, the upper end of the movable rod is fixedly connected to the limiting cover, the two ends of the telescopic spring are respectively connected to the lower surface of the top plate and the upper surface of the upper protective plate, and the two ends of the extrusion spring are respectively connected to the inner wall of the device frame and the side wall of the extrusion plate.

[0009] Preferably, two ends of the return spring are respectively connected to the lower surface of the upper connecting block and the upper surface of the lower connecting block, and two ends of the extrusion spring are respectively connected to the side wall of the extrusion plate and the inner wall of the device frame.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. When the outside world impacts the protection frame, the pressure impacts the top plate, the top plate sinks and transmits the force to the telescopic column, the reset spring is compressed, and the top plate generates shear force through the telescopic column and the non-Newtonian fluid in the sleeve, which increases the resistance force of the non-Newtonian fluid and offsets the impact force on the telescopic column, thereby playing a shock-absorbing role. After the impact force disappears, the reset spring drives the top plate to reset. Through the cooperation between the telescopic column, sleeve, reset spring and non-Newtonian fluid, the impact of the protection frame each time it is subjected to external impact is reduced, thereby increasing the service life of the protection frame and protecting the use of the pipeline body.

[0012] 2. The staff opens the device frame and the device frame wall, installs the pipeline body on the lower protective plate, closes the device frame and the device frame wall and fixes them through threaded rods. The threaded rods make it easy to disassemble the device during later replacement or maintenance, and squeeze the upper protective plate through the telescopic spring. The squeezing spring squeezes the squeezing plate and the squeezing plate drives the lower protective plate upward through the connecting rod, thereby clamping the pipeline body, so that the pipeline body remains stable during the construction process to prevent the pipeline body from shaking.

[0013] 3. When the top plate sinks, it drives the telescopic spring to squeeze the upper protective plate. The upper protective plate sinks and squeezes the lower protective plate through the pipeline body, so that the lower protective plate moves downward. The lower protective plate drives the connecting rod to squeeze the extrusion plate, so that the extrusion plate moves outward. By converting the impact force on the top plate into downward kinetic potential energy, it further plays a shock-absorbing role, and utilizes the elasticity of the extrusion spring and the telescopic spring to make the upper and lower protective plates protect the pipeline body, avoiding the impact force directly transmitted to the pipeline body and causing damage to the pipeline body, thereby increasing the service life of the pipeline body.
